Stephen Hawking on Black Holes and Why He’d Be a Good Bond Villain

Stephen Hawking on Black Holes and Why He’d Be a Good Bond Villain

Stephen Hawking always starts his lectures with the same quip: “Can you hear me?” His characteristic delivery, a blend of humor and complicated theoretical physics, is the kind of performance that Hawking, 72, is now well known for, even as he has become a celebrity ambassador for science, a physicist whose office is adorned with portraits taken with Barack Obama, Bill Clinton and Steven Spielberg (twice) as well as stills from his many appearances in Star Trek and The Simpsons.

How to Check if Your Universe Should Exist

How to Check if Your Universe Should Exist

If modern physics is to be believed, we shouldn’t be here. The meager dose of energy infusing empty space, which at higher levels would rip the cosmos apart, is a trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion times tinier than theory predicts. And the minuscule mass of the Higgs boson, whose relative […]

How Gravity Explains Why Time Never Runs Backward

We can’t avoid the passing of time, even at the DMV, where time seems to come to a standstill. And daylight savings notwithstanding, time always ticks forward. But why not backward? For a group of physicists, the answers to these deep and complex questions may arise from a familiar source: gravity.
